What Is a Convertible Under Cabinet Range Hood?

Updated on · By the Got Vents team

A convertible under cabinet range hood can vent air outdoors through ductwork or recirculate it through filters, depending on how you install it. Check the hood's vent openings, filters, and your kitchen's duct route before choosing a mode.

A convertible under cabinet range hood can vent air outdoors through ductwork or recirculate it through filters, depending on how you install it. Check the hood's vent openings, filters, and your kitchen's duct route before choosing a mode.

The main difference is where the air goes. Ducted mode carries cooking air outside, while recirculating mode filters it and returns it to the room.

What does convertible mean on a range hood?

Convertible means a range hood supports more than one venting setup. A model may allow ducted exhaust, ductless recirculation, or both, depending on its design and the parts included or required.

An under cabinet hood sits beneath a kitchen cabinet above the cooktop. Its compact location affects how the duct can leave the hood, such as through the top or back.

A convertible model gives you options for matching that outlet to your kitchen.

The word doesn't mean every installation is interchangeable without changes. The instructions may call for a different damper, vent cover, or filter when you switch modes.

How do ducted and recirculating modes differ?

Ducted mode sends air outside, while recirculating mode returns filtered air to the kitchen. Choose based on the duct path available and the hood's approved setup.

With ducted exhaust, a fan pulls cooking air through a filter and pushes it into a duct that leads outdoors. Grease filters help catch grease from the air, but the duct route and connections still need to suit the hood.

With recirculation, the hood draws air through filters and releases it back into the room. A charcoal filter may be needed to help reduce odors.

It doesn't create an outdoor exhaust route.

For more detail on that second setup, see how a recirculating range hood works. If you're weighing the two installation choices, our guide to convertible vs. ducted range hoods explains what changes.

How do you tell which mode your kitchen can support?

Look for a usable duct path to an exterior wall or roof before planning ducted installation. If you don't have one, check whether the hood allows recirculation and what filter it requires.

Measure the cabinet and the space above the cooktop, then locate the hood's exhaust opening. Some models support vertical top venting, horizontal rear venting, or both.

Your chosen route must line up with the hood and the duct path.

If you use recirculation, confirm where filtered air exits the hood and that it won't be blocked by the cabinet. Check the manual for the filter type and any changes needed to the damper or vent cover.

Does convertible mean the hood can vent in any direction?

No. A convertible hood has defined outlet positions and installation steps; it won't necessarily support every direction.

For example, the SNDOAS USGF3976S supports vertical top venting and horizontal rear venting, and it can also be installed for ductless use. Its instructions specify an exhaust pipe for ducted use and a carbon filter for ductless use.

Check the cabinet opening and the wall or ceiling route against the manual before buying. If you need a ducted installation, note that this model's exhaust pipe is not included.

What parts and filters might a convertible hood need?

The mode determines which parts and filters the installation needs. Ducted setups need a compatible path outdoors; recirculating setups may need a charcoal filter and an open return-air path.

Many hoods include a grease filter, which catches grease before it builds up inside the unit. A charcoal filter serves a different purpose in recirculating mode by helping reduce odors.

One filter type doesn't automatically replace the other.

The COMFEE' CVU30W4AST has a reusable, dishwasher-safe aluminum filter and supports both exhaustion and recirculation modes. Its 30 in width may suit a matching under cabinet space, but measure your cabinet and cooktop area before choosing.

The Broan-NuTone PrintGuard Convertible 30 Inch has a removable, dishwasher-safe aluminum filter and a two-speed blower. Its flexible installation design supports different ducting needs.

For recirculation, choose a charcoal filter specified for your hood model. The beaufan CFK1-TM set is compatible with certain COSMO range hood models, including UC30 and UMC30, but it isn't a universal replacement.

Check the exact model and filter part number before ordering. See our guide to ductless under cabinet range hoods for more options designed for recirculation.

What should you check before installation?

Confirm the hood's dimensions, vent position, electrical connection, and required parts before starting. The instructions for your exact model should guide the installation.

Compare the hood's width and depth with the available cabinet space. Then map the exhaust opening to the duct route, if you plan ducted use.

Check whether the unit is hard-wired or has a plug, since the electrical setup varies by model.

If you're replacing an existing hood, don't assume the old duct opening or wiring will match. Our guide to replacing an under cabinet range hood covers the checks to make before removing the old unit.

Never block the hood's return-air opening in recirculation mode. For ducted mode, use the duct type and route approved in the installation instructions.

Is a convertible hood right for your kitchen?

Choose a convertible hood if you want to match the installation to either a suitable outdoor duct route or a supported recirculation setup. Decide which mode you'll use before comparing models, since the required parts and filter care differ.

Pick ducted mode when you have a compatible path outside and want air exhausted from the kitchen. Pick recirculation when no practical duct route is available and the hood supports that mode with the right filter.

A convertible under cabinet range hood gives you flexibility, but the cabinet opening, vent direction, electrical setup, and filter needs still determine whether a specific model fits. Use the instructions to confirm the installation, then compare under cabinet range hood options that match your kitchen.

Frequently asked questions

What does convertible mean on a range hood?

Convertible means the hood can be set up for ducted exhaust or ductless recirculation, if its design supports both modes. Ducted installation sends air outdoors through a duct.

Recirculation sends air through filters and back into the kitchen.

Check the required filters, vent opening, and installation instructions for the exact model.

Is a convertible range hood always ductless?

No. Convertible describes the available installation options, not the mode the hood is using at any given time.

A hood set up for ducted exhaust needs a suitable duct route to the outdoors.

In recirculation mode, it needs the correct filters and a path for filtered air to return to the room.

Do convertible range hoods need charcoal filters?

Charcoal filters are generally used for recirculating mode to help reduce cooking odors before air returns to the kitchen. The required filter depends on the hood model.

Check its instructions for the correct part and replacement schedule, and don't assume a carbon filter is included.

Can I change a convertible hood from ducted to ductless?

Often, but the change depends on the hood's design and the kitchen setup. You may need to add a compatible charcoal filter, change a damper or vent cover, or adjust the exhaust direction.

Follow the model's instructions, and check whether the cabinet and outlet arrangement allow the conversion.
